Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a front floor assembly and a vehicle. Background Technology

[0002] Currently, the front floor of a vehicle, as a key component of the passenger compartment, must not only meet the performance requirements of the passenger compartment's bottom structure, such as impact resistance and rigidity, but also accommodate the installation of components such as seats, drive shafts, and power batteries. Existing front floor structures are becoming increasingly complex in their design to meet automotive collision safety regulations (such as side impact and pole impact requirements), leading to increased costs. Utility Model Content

[0003] This application provides a front floor assembly that effectively saves manufacturing costs and improves the overall strength and stability of the structure.

[0004] This application also proposes a vehicle that includes the aforementioned front floor assembly.

[0005] According to an embodiment of this application, a front floor assembly includes: a front floor body; a crossbeam, the crossbeam being disposed on the upper side of the front floor body, the crossbeam extending along the left-right direction of the vehicle, the crossbeam being a plurality of crossbeams spaced apart along the front-rear direction of the vehicle, at least one of the crossbeams having a plurality of spaced cavities, the cavities penetrating the crossbeam along the left-right direction, the front floor body and the plurality of crossbeams being integrally extruded.

[0006] According to the embodiments of this application, the front floor assembly, by providing multiple crossbeams spaced apart along the longitudinal direction of the vehicle on the upper side of the front floor body, and at least one crossbeam having multiple spaced cavities, greatly increases the local stiffness and overall strength of the crossbeams, enabling them to more effectively resist bending and torsion from all directions. The front floor body and multiple crossbeams are integrally extruded, reducing the number of parts and assembly complexity of the front floor assembly, simplifying the manufacturing process, reducing process connection points, and effectively saving manufacturing costs. It also improves the overall strength and stability of the structure, avoiding potential quality problems and performance losses caused by connection processes; and simultaneously enhances the vehicle body's crashworthiness and stiffness.

[0007] In some embodiments of this application, the plurality of crossbeams include: a front seat crossbeam, the front seat crossbeam having a plurality of cavities, the plurality of cavities including a plurality of first sub-cavities, the plurality of first sub-cavities being spaced apart along the longitudinal direction of the vehicle. The front seat crossbeam is used to mount a seat, the seat's slide rail being fixed to the front seat crossbeam, realizing the seat mounting function of the front floor assembly, and achieving functional integration of the front floor assembly. The first sub-cavities distributed along the longitudinal direction can disperse and absorb the collision energy received by the front seat crossbeam in the longitudinal direction, reducing the collision energy transmitted to the seat above.

[0008] In some embodiments of this application, the plurality of cavities within the front seat crossbeam further include a second sub-cavity, the second sub-cavity being located above the plurality of first sub-cavities. This can further protect the vehicle body, better absorb the collision energy transmitted to the seat when the vehicle is involved in a collision, improve the vehicle's collision safety performance, and protect the safety of the occupants in the seat.

[0009] In some embodiments of this application, there are multiple front seat crossbeams, which are spaced apart along the longitudinal direction of the vehicle. This ensures the seat installation function of the front floor assembly, achieving functional integration of the front floor assembly. Simultaneously, the multiple front seat crossbeams are all connected to the left and right sill beams of the vehicle body, which can resist side impacts, pole impacts, and other collision forces, ensuring vehicle body rigidity.

[0010] In some embodiments of this application, the plurality of crossbeams further include: a first crossbeam and a second crossbeam, wherein the first crossbeam and the second crossbeam are respectively disposed on the front and rear sides of the front seat crossbeam. This enhances the force transmission effect of the left and right sill beams on the left and right sides of the vehicle body.

[0011] In some embodiments of this application, at least one of the first crossbeam and the second crossbeam has a plurality of said cavities, which are spaced apart along the vertical direction of the vehicle. The first crossbeam and / or the second crossbeam transmits collision energy vertically, while the front seat crossbeam transmits collision energy forward and backward, which can more evenly disperse and transmit the huge collision force, avoid excessive stress concentration that could lead to sudden structural failure, and thus ensure the integrity of the passenger compartment.

[0012] In some embodiments of this application, the first crossbeam is located in front of the second crossbeam, and the upper end face of the first crossbeam is lower than the upper end face of the second crossbeam. This can reduce the damage to the front bulkhead after the first crossbeam absorbs collision energy and avoid damage to other components in the engine compartment.

[0013] In some embodiments of this application, the two sidewalls of the crossbeam along the longitudinal direction of the vehicle are inclined towards each other in an upward direction. This facilitates the demolding of the front floor assembly from the extrusion mold and allows for better absorption and transfer of impact energy from the front floor body.

[0014] In some embodiments of this application, the front floor body and the crossbeam are integrally extruded aluminum parts. The aluminum parts are lightweight, achieving vehicle weight reduction.

[0015] The vehicle according to an embodiment of this application includes the aforementioned front floor assembly.

[0016] According to an embodiment of this application, a vehicle is provided with a front floor assembly. By placing multiple crossbeams spaced apart along the longitudinal direction of the vehicle on the upper side of the front floor body, and at least one crossbeam having multiple spaced cavities, the local stiffness and overall strength of the crossbeams are greatly increased, and the crossbeams can more effectively resist bending and torsion from all directions. The front floor body and multiple crossbeams are integrally extruded, reducing the number of parts and assembly complexity of the front floor assembly, simplifying the manufacturing process of the front floor assembly, reducing process connection points, and effectively saving manufacturing costs of the front floor assembly; it also improves the overall strength and stability of the structure, avoiding potential quality problems and performance losses of the front floor assembly caused by connection processes; and at the same time, it improves the vehicle body's crashworthiness and stiffness.

[0019] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] The front floor assembly 100 according to an embodiment of this application is described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the front floor assembly 100 according to an embodiment of this application includes a front floor body 1 and a crossbeam 2.

[0022] Specifically, the front floor assembly 100 is typically located below the front axle of the vehicle, and the front floor assembly 100 is positioned along the left-right direction of the vehicle (e.g., Figure 1 Extending in the left-right direction (as shown), the load-bearing structure connects the two sides of the vehicle body and can bear the weight of the vehicle body as well as the load from components such as the engine. Furthermore, the crossbeam 2 is located on the upper side of the front floor body 1 and extends in the left-right direction of the vehicle. As an important component of the bottom structure of the vehicle body, the front floor body 1 undertakes the task of bearing the weight of the vehicle body and the load, and can evenly distribute the weight of the vehicle body and the load during driving to other parts of the vehicle body, ensuring the stability and safety of the vehicle.

[0023] Crossbeam 2 runs along the front-to-back direction of the vehicle (e.g., Figure 1 Multiple crossbeams (as shown in the front-rear direction) are spaced apart. During vehicle operation, especially when cornering or traversing bumpy roads, the vehicle body experiences forces from different directions, leading to torsional deformation. Crossbeam 2 tightly connects the left and right ends of the vehicle's bottom, forming a robust frame structure that significantly improves the vehicle's torsional rigidity. In the event of a collision, the front floor crossbeam 2 effectively disperses and transmits some of the impact force to the sides of the vehicle body, preventing the impact force from being concentrated on the front bulkhead and passenger compartment, thereby reducing passenger compartment deformation and protecting the safety of occupants. Furthermore, by increasing the rigidity of the front floor assembly by 100%, crossbeam 2 effectively reduces the transmission of vibrations from the chassis and road surface into the passenger compartment, while also reducing noise generated by panel vibration, thus improving ride comfort.

[0024] At least one crossbeam 2 has multiple spaced cavities 24 that extend through it in the left-right direction. The presence of these cavities 24 further protects the vehicle body, absorbs collision energy, improves collision safety performance, and protects the safety of occupants. By incorporating multiple cavities 24, the local stiffness and overall strength of the crossbeam 2 are significantly increased. The crossbeam 2 can more effectively resist bending and torsion from all directions; and it can more smoothly and evenly disperse and transfer the enormous collision force, avoiding excessive stress concentration that could lead to sudden structural failure, thereby ensuring the integrity of the passenger compartment.

[0025] The front floor body 1 and multiple crossbeams 2 are integrally extruded, which reduces the number of parts and assembly complexity of the front floor assembly 100, simplifies the manufacturing process of the front floor assembly 100, reduces process connection points, and effectively saves the manufacturing cost of the front floor assembly 100; it also improves the overall strength and stability of the structure, avoids potential quality problems and performance loss of the front floor assembly 100 caused by connection processes; and improves the vehicle body's crash resistance and rigidity.

[0026] In this embodiment, multiple crossbeams 2 simultaneously connect the left sill beam 20 and the right sill beam 30 to resist side impacts, pole impacts, and other collision forces and ensure the rigidity of the vehicle body.

[0027] According to the embodiments of this application, the front floor assembly 100, by providing a plurality of crossbeams 2 spaced apart along the longitudinal direction of the vehicle on the upper side of the front floor body 1, and at least one crossbeam 2 having a plurality of spaced cavities 24, greatly increases the local stiffness and overall strength of the crossbeams 2, enabling the crossbeams 2 to more effectively resist bending and torsion from all directions. The front floor body 1 and the plurality of crossbeams 2 are integrally extruded, reducing the number of parts and assembly complexity of the front floor assembly 100, simplifying the manufacturing process of the front floor assembly 100, reducing process connection points, and effectively saving manufacturing costs of the front floor assembly 100; it also improves the overall strength and stability of the structure, avoiding potential quality problems and performance losses of the front floor assembly 100 caused by the connection process; and at the same time improves the vehicle body's crashworthiness and stiffness.

[0028] In this embodiment, the front floor body 1 and the crossbeam 2 are integrally extruded using an extrusion die.

[0029] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the multiple crossbeams 2 include a front seat crossbeam 21, which is used to install the seat. The seat slide rail is fixed on the front seat crossbeam 21, realizing the seat installation function of the front floor assembly 100 and realizing the functional integration of the front floor assembly 100.

[0030] The front seat crossbeam 21 has multiple cavities 24, including multiple first sub-cavities 241. These first sub-cavities 241 are arranged at intervals along the longitudinal direction of the vehicle. The multiple first sub-cavities 241 can protect the vehicle body by absorbing the collision energy transmitted to the seat during a collision, thus improving the vehicle's collision safety performance and protecting the safety of the occupants. Furthermore, the longitudinally distributed first sub-cavities 241 can disperse and absorb the collision energy received by the front seat crossbeam 21 in the longitudinal direction, reducing the collision energy transmitted to the seat above.

[0031] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the multiple cavities 24 within the front seat crossbeam 21 also include a second sub-cavity 242. The second sub-cavity 242 is located above the multiple first sub-cavities 241. By setting the second sub-cavity 242, the vehicle body can be further protected, and the collision energy transmitted to the seat can be better absorbed when the vehicle is involved in a collision, thereby improving the collision safety performance of the vehicle and protecting the safety of the occupants in the seat.

[0032] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, there are multiple front seat crossbeams 21, which are spaced apart along the front-rear direction of the vehicle. The seat rails are fixed on the multiple front seat crossbeams 21 to ensure the stability of the seat, thereby improving the reliability and stability of the seat installation and ensuring the seat installation function of the front floor assembly 100. This realizes the functional integration of the front floor assembly 100. At the same time, the multiple front seat crossbeams 21 are all connected to the left sill beam 20 and the right sill beam 30 of the vehicle body, which can resist the collision forces such as side impact and pole impact, and ensure the rigidity of the vehicle body.

[0033] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the multiple crossbeams 2 also include a first crossbeam 22 and a second crossbeam 23, which are respectively located on the front and rear sides of the front seat crossbeam 21. The first crossbeam 22 and the second crossbeam 23 are both connected to the left sill beam 20 and the right sill beam 30 of the vehicle body, which can resist the impact forces of side collisions, pole collisions, etc., and ensure the rigidity of the vehicle body; and increase the force transmission effect of the left sill beam 20 and the right sill beam 30 on the left and right sides of the vehicle body.

[0034] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, at least one of the first crossbeam 22 and the second crossbeam 23 has a plurality of cavities 24, the plurality of cavities 24 being along the vertical direction of the vehicle (e.g., Figure 1 The beams are arranged at intervals in the vertical direction shown. It can be understood that the first crossbeam 22 has multiple cavities 24, or the second crossbeam 23 has multiple cavities 24, or both the first crossbeam 22 and the second crossbeam 23 have multiple cavities 24.

[0035] By setting multiple cavities 24 spaced apart along the vertical direction of the vehicle, the local stiffness and overall strength of the first crossbeam 22 and / or the second crossbeam 23 are greatly increased, which can more effectively resist bending and torsion from all directions. At the same time, the front seat crossbeam 21 has multiple first sub-cavities 241 spaced apart along the longitudinal direction of the vehicle. The first crossbeam 22 and / or the second crossbeam 23 transmit the collision energy vertically, and the front seat crossbeam 21 transmits the collision energy longitudinally. This can more evenly disperse and transmit the huge collision force, avoid excessive stress concentration which could lead to sudden structural failure, and thus ensure the integrity of the passenger compartment.

[0036] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the first crossbeam 22 is located in front of the second crossbeam 23. The upper end face of the first crossbeam 22 is lower than the upper end face of the second crossbeam 23. The first crossbeam 22 is closer to the engine compartment at the front of the vehicle. The fact that the upper end face of the first crossbeam 22 is lower than the upper end face of the second crossbeam 23 can reduce the damage to the front bulkhead after the first crossbeam 22 absorbs the collision energy and avoid damage to other components in the engine compartment.

[0037] Of course, this utility model is not limited to this. Alternatively, the first crossbeam 22 may be located behind the second crossbeam 23, with the upper end face of the first crossbeam 22 being lower than the upper end face of the second crossbeam 23; or the upper end face of the first crossbeam 22 may be roughly flush with the upper end face of the second crossbeam 23. The choice can be made according to design requirements.

[0038] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, in the direction from bottom to top, the two side walls of the crossbeam 2 along the front-rear direction of the vehicle are inclined toward each other, which facilitates the demolding of the front floor assembly 100 from the extrusion mold; at the same time, it can better absorb and transfer the collision energy of the front floor body 1.

[0039] In some embodiments of this utility model, the front floor body 1 and the crossbeam 2 are integrally extruded aluminum parts. The crossbeam 2 can be better extruded into a hollow crossbeam 2, integrating the crossbeam 2 and the front floor body 1 into a single extruded part, simplifying the structure of the front floor assembly 100. Furthermore, the aluminum part is lightweight, achieving vehicle weight reduction.

[0040] The vehicle according to an embodiment of this application includes a front floor assembly 100.

[0041] According to the vehicle embodiment of this application, a front floor assembly 100 is provided. By placing a plurality of crossbeams 2 spaced apart along the longitudinal direction of the vehicle on the upper side of the front floor body 1, and at least one crossbeam 2 having a plurality of spaced cavities 24, the local stiffness and overall strength of the crossbeams 2 are greatly increased, and the crossbeams 2 can more effectively resist bending and torsion from all directions. The front floor body 1 and the plurality of crossbeams 2 are integrally extruded, which reduces the number of parts and assembly complexity of the front floor assembly 100, simplifies the manufacturing process of the front floor assembly 100, reduces process connection points, and effectively saves the manufacturing cost of the front floor assembly 100; it also improves the overall strength and stability of the structure, avoids potential quality problems and performance losses of the front floor assembly 100 caused by the connection process; and at the same time improves the vehicle body's crashworthiness and stiffness.
